Unsure as to times, but basic schedule is one trip each way per day between Toledo and a siding just north of Ann Arbor called Osmer. Interchange at Osmer with Great Lakes Central, mainly sand cars from/to Yuma. AA's customers include (this is not a complete list) of course the interchange of (mainly) sand cars with GLC at Osmer; interchange with NS in Milan; a couple of places around Whitmore Lake (small factories); AHC (auto parts) at the end of the Saline Branch, which runs for a couple of miles southeast off the main at Pitt Jct; the cement plant in Dundee (I believe this closed recently), and its Toledo customers. These include Jeep, Kraft Foods, GM (the latter two via trackage rights on CSX to AA's orphan Temperance Yard), and a mixing facility which I believe is owned by Ford. I am probably missing some. AA's traffic, which has always been fairly strong, is probably off in the last year or so on account of the severe economic downturn in southern Michigan and northern Ohio.
